2. Use an angled insert to reduce the size of the remaining boss.

3. Use a sharp-cornered lead-angled insert to make the remaining boss much smaller when machining small parts and thin parts.

¢ Caution

1. For TKN and TK

, set the cutting edge height 0.1~0.2mm above the center height (Fig. 3)

For other toolholders, set the cutting edge to the center height.

2. Be sure to perform wet processing. Apply enough coolant to the cutting edge.

3. Keep a constant rate during processing so that optimum product life will be achieved.

4. Cut-off as close to the chuck as possible.

5. Lower the feed rate to 1/2 to 1/3 at the near center to prevent impact caused by machining.

Overuse of insert and toolholder (blade) may cause insert breakage and toolholder (blade) damage.

Do not rework the insert and toolholder (blade) to prevent damage.

Clean the insert pocket well with compressed air when replacing insert.



Caution (Cut-Off)

1. Be sure to perform wet processing. Apply enough coolant to the cutting edge.

2. Keep a constant rate during processing so that optimum product life will be achieved.

3. Cut-off as close to the chuck as possible.

4. Lower the feed rate to 1/2 to 1/3 at the near center to prevent impact caused by machining.

Series Advantage

GMM-MT

Specific chipbreaker for cut-off operations requiring sharp cutting performance.

Minimizes the Boss.

GMM-NB

Cutting edge is flat with non-chipbreaker.

Good performance for brass, etc.

GMM-TK

Stable design with chipbreaker for cut-off. Large corner-R.

2-edge for economical performance.

GMN-TK

Same chipbreaker geometry as GMM-TK.

1-edge. Wide application range.

GMN (Std.)

(No Indication)

Mainly for deep grooving, but available for groove widening and turning due to projection near side cutting edge.

1-edge and wide application range. Available for cut-off applications.

1. Tap the insert lightly with a plastic hammer to push it into the extent that it can

not be removed by hand. (Fig.1)

(Pull it to the point where it does not fall out when picked up lightly with a finger)

2. Remove the insert with the supplied wrench. (Fig.2)
